I compose and perform electronic music and sometimes I get tire of clean,cold and docile sounds so I had to create something dirty,noisy and almost untamed,Thats how Crespell came to live.
Crespell is a primitive synthesizer built from good old logic microchips (CMOS). Inside this little monster there is a square wave oscillator with 4 sub-oscillators, each one a octave away from the previous one and with independent level potentiometers, you can think of each sub-oscillator like harmonics on a Hammond style organ.
To control the dynamics I built a low pass filter with resonance and overdrive to give extra character to the sound. pitch and dynamic can be controlled with light (the light sensor are under the gems). As a way to control the untamed beast I added a primitive keyboard for pitch control and the filter can act like a low pass gate if its controlled with a voltage sequencer. Pitch can also be sequenced with an external multiplexer-based "resistor sequencer". All presented on a organic/rustic enclosure.
